Apply the following steps to an Agent instance. If an Agent cluster is operated then steps are performed for any Agent cluster member.

...

Note: A restart of the Agent instance is required to apply patches.

Apply Patch to Agent Docker® Containers

The Agent container expects Java .jar libraries for patches from the following location:

• /var/sos-berlin.com/js7/agent/config/lib
• The directory /var/sos-berlin.com/js7/agent typically is mounted to a Docker var volume when running the container: for details see JS7 - Agent Installation for Docker Containers.
• If the sub-directory config/lib does not exist then it can be created before storing the patch file.

Apply Patch

On start-up the Agent container checks the above directory for existence of .jar files and applies the patches, for details see chapter On Premises.

Patches are not applied persistently to a container. Therefore patch files remain in place in the /var/sos-berlin.com/js7/agent/config/lib sub-directory (typically mounted to the config/lib volume directory) as long as the patch should be applied.

Note: A restart of the Agent container is required to apply patches.

Remove Patch

Patches are removed by dropping the files in the patches sub-directory.
